English language proficiency testing and flight crew licensing

Read the official rule

The UK Civil Aviation Authority outlines the process for assessing English Language Proficiency (ELP) required for flight crew licenses. Assessments can be formal or informal, with various criteria for different proficiency levels. Candidates may need to be referred to approved testing bodies if they cannot demonstrate sufficient language skills, particularly for the highest proficiency level.

Key points

  • ELP assessments can be formal or informal, conducted by licensed examiners.
  • Level 6 proficiency is considered expert level, but not strictly required for safe aeronautical communication.
  • Informal assessments must meet strict criteria, including thorough documentation of a candidate's linguistic background.
